Abstract

UN SISTEMA DE PROYECCION INCORPORA UNA PANTALLA (2, 14) CON UNA RESPUESTA SUSTANCIALMENTE ACROMATICA EN UNA DIRECCION SUSTANCIALMENTE PERPENDICULAR AL PLANO DE LA PANTALLA. LA PANTALLA (2, 14) COMPRENDE UNA REJILLA DE DIFRACCION (4), MEDIOS (5) PARA ATENUAR EL ORDEN CERO Y UN ELEMENTO OPTICO HOLOGRAFICO DIFUSO (6). EL SISTEMA COMPRENDE ADEMAS UN ELEMENTO DE ENFOQUE CON UNA POTENCIA OPTICA POSITIVA. LA POTENCIA OPTICA ACUMULADA DE LA REJILLA Y DEL ELEMENTO OPTICO HOLOGRAFICO ES SUSTANCIALMENTE MENOR QUE LA DEL ELEMENTO DE ENFOQUE.
